Dance teacher sent girls texts 'at all hours'

A Sydney court has refused bail to a well-known dance teacher accused of child pornography and abuse offences as it emerged he allegedly sent thousands of text messages to underage girls at all hours of the night.

Grant Davies, the former co-director of RG Dance in Sydney's inner west, was charged with an extra 37 charges on Tuesday.

Today, he applied for bail but Justice Carolyn Simpson said the electronic evidence was too strong to allow his release, The Sydney Morning Herald reports.

The prosecution said police found messages sent to several girls in a "pattern of behaviour that has been quite intense for a number of years".

Justice Simpson said there was no way to be sure Davies would not try to contact victims if he was released.

"History shows Davies has made prolific use of electronic media in contacting children for sexual purposes," she said.

The 39-year-old is accused of grooming, sexually assaulting and taking naked photos of students aged between nine and 14 over more than a decade.
